Title: Optical information recording medium, optical information recording and reproducing method and device
Inventor: NODA KAZUO
IPC: G11B7/2407
Filed: 1994-06-15
Abstract: PURPOSE:To efficiently record both of pit information and bar code information by containing a plurality of guide tracks in a second recording region for recording bar code information. CONSTITUTION:The part of a guard track 8 in, the top part is used as a region for recording bar code information. A plurality of guide tracks 3 are provided in parallel at a predetermined pitch (P) in the region 5 as in the other region 2. The tracks 3 in the region 5 are not formed of continuous straight line but the part 3a of different reflectance is intermittently provided. This is because the bar part of a bar code can be formed for recording even in the part of the tracks 3. The recording of bar code information to the region 5 is performed by using the same optical head as one which is used for pit information. However, since the recording operation for bar code information is different from the recording operation for pit information, the operation is performed by two recording modes, and the bar code information is recorded in continuous or intermittent paint-out form over the range of tracks.

Measured values by the measurement part 15 are converted  into electric signals, which after being amplified by an amplification part 20, are inputted to a comparison arithmetic part 21. The comparison arithmetic part 21 compares  the input with the upper limit set value of graunlarity or number distribution set to a setting part 22 and, when a signal exceeding the set value is inputted, it sends an output signal to an output part 23 to discriminate the occurrence of an internal fault. This constitution enables to circulates the sample oil through a closed circuit, so the oil never comes into contact with the external air, so that the deterioration of insulation  reliability due to sample collection never occur.

Abstract: PURPOSE:To enable measurement of an eye refraction value with a simple construction without use of a separation prism by receiving a reflected luminous flux from an eyegrounds on a light position detector through an objective lens and an luminous flux division member. CONSTITUTION:Luminous flux from a light source 1 travels on an optical axis 01 to be projected onto an eyeground Er of an eye E to be inspected as spot luminous flux via a lens 2, an opening 3a of a stop 3, a hole of a perforated mirror 4 and an object lens 5. The reflected luminous flux by the eyeground Er returns on the same optical path to be reflected with the perforated mirror 4 and four luminous fluxes Ma-Md are projected onto an image sensor 8 via a stop 6 and a lens 7. A diameter (d) of the reflected luminous flux from the eyeground Er differs on a plane R vertical to the optical axis 01 at a point Q according to condition of the eye E to be inspected. The diameter (d) of the luminous flux is proportional to an eye refraction, namely, a diopter value of the eye E to be inspected. Thus, an eye refraction to a longitudinal direction aligning the reflected luminous fluxes Ma and Mc of that to a longitudinal direction aligning the reflected luminous fluxes Mb and Md can be calculated from an interval between the reflected luminous fluxes Ma and Mc having an optical axis 02 therebetween or an interval between the reflected luminous fluxes Mb and Md on the image sensor 8 arranged at a position conjugated to a point Q.
